Inequality symbols

Inequality symbols can be used to show which number is greater. For example, -2 \textless -1 means -2 is less than -1. The wider part of the inequality sign faces the larger number.

-1 \textgreater -2 means -1 is greater than -2 because -1 is further to the right of -2 on the number line.
